To all wlw/n, it may concern:

Be it known' that I, FRANK L. Boonmrr, a citizen of the United States, residing at New Brunswick, in the county of\Middlesex and State of New Jersey, have invented new and useful Improvements in Envelops, of which the following is a specification.

This invention relates to envelops.; and it has for its primary object the provision of an article of this character which will be particularly adapted for use by commercial houses, correspondence schools or other like places of business and which will include a retaining pocket for the reception of return postage, the pocket being so constructed whereby to permit of the convenient removal of the postage by the addressee, while further formed so as to prevent of its being fraudulently tampered with without detection.

IVith the above and other objects in view, the invention consistsof certain novel features of construction, combination and a1.'- rangement of parts, as will be hereinafter described and claimed.

In the accompanying drawings:--Figure 1 is a plan view of the blank from which the main body of the envelop is constructed, illustrating the application of the pocket member thereto; Fig. 2 is a vertical longitudinalv section through the envelop and through the pocket; Ilig. 3 is a. plan view of the pocket forming member; and Fig. 4 is a plan view of the sealing element thereof. s

The envelop is constructed from a single blank of suitable material and is formed with a main body 1, side flaps 2 folded 4over and secured together` adjacent their free marginal edges, an end flap 5 folded over and secured to the side 4Ilaps- 2, and an upper sealing flap 6, the latter having an adhesive 7 at one side which may be gummed to permit the flap to be folded over the open upper end `of the envelop and then secured to the side flaps 2 in the usual well known manner.

The pocket designed for the reception of stamps for return postage comprises a single blank 8 of material curved longitudi` nally along its upper edge, as at 9, and gummed on its inner surface adjacent the side edges and lower horizontal edge of the rthis member is adapted to be secured to the inner wall of the body l of the envelop and arranged thereon so as to define therewith an' intervening pocket 11, as s hown in Fig. 2 of the drawings.

"lhe sealing member for the pocket/comprises a singlestrip of material 12 having a. maximum width approximately equal to the width of the blank S and provided with an upper sealing flap 13 normally overlying l and free from the open end of the pocket and provided with an adhesive 14:, which may be moistened so that when the flap is folded over the open end of the pocket it may be secured to the blank 8, so as to hold the articles contained in the pocket against accidental loss. The blank l2 is reduced in width below its sealing ila-p so as to provide an attaching portion 15 having an adhesive on one side, as at 1G, which may be moistened and secured to the inner surface of the body portion l of the envelop.

To facilitate the operation of removing the contents of the pocket, I provide a tearing element 17 which may be in the form of a single strip of fiexible material, such as cord or light wire having a length exceeding the length of the pocket so that the eX- tremities of the element will be extended beyond the ends of the sealing liap 1? of the portion and exposed whereby they may be freely manipulated and pull applied thereto so that pressure can be brought to bear against the flap 13 along its length of fold with the blank 12 with a resultant separation of the sealing llap from the main body portion of the blank or attaching portion thereof, as will be obviously understood.

From the foregoing description, taken in connection with the accompanying drawings, the construction and operation of the invention will be readily understood witliout requiring a more extended explanation.

Various changes in the form, proportion land the lninor details ot construction may be resorted to without departing from the principle or sacrificing any of the advantages of thisinvention as claimed.

Having thus described my invention, what I claim is :-q

1. An envelop, a blank of material sccured adjacent its marginal edges to one of the inner falls of the envelop and associated relatively of such wall so as to define therewith an interi'cning pocket, a blank of material interposed between the inner wall and said first blankand secured to the inner wall and having a sealing flap foldable over the open end of the pocket defined from the first blank and the inner Wall of the envelop and secured to the outer wall of said first blank.

2. An article holding pocket7 for envelops comprising a blank secured adjacent its1narginal edges to one of the Walls of the envelop adjacent the sealing flap thereof, a blank interposed betweenv one of *he Walls of the envelop .and the first blank and having an attaching portion secured to the envelop and a flat portion normally free from the envelop and provided with an adhesive and adapted to be folded over and against FRANK LOUIS BOCHERT.
